Since the conventional energy monitoring apparatuses using AMI or AMR, digital power meters measure only total usage information of the total power energy generated by the combination of the individual utilization equipments after the installation time thereof, multiple individual energy measuring apparatuses must be installed or an energy measuring apparatuses using multiple sensors must be installed within the switchboard in order to extract the energy usage information of the individual utilization equipments.

Above described objectives, features and advantages will be more apparent through the following detailed descriptions related to the accompanying drawings, thus a person of ordinary skill in the art may easily implement the technical spirit of the present invention.

A detailed description of a publicly known prior art related to the present invention will be omitted if determined that it may unnecessarily obscure the gist of the present invention. Hereinafter, it will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating an energy measuring apparatus 100 according to an exemplary embodiment of the present invention.

In this exemplary embodiment, in order to estimate the amount of the energy consumption of the individual facility equipments being connected to the penetration point and the internal components thereof from the total energy of the power consumption of the penetration point, an energy measuring apparatus 100 performs hardware algorithms which generate unregistered load clustering data sets, and transmits these to a specific server or a cloud 200.

In other words, an energy measuring apparatus 100 according to an exemplary embodiment of the present invention is installed at penetration point of power with a single sensor and embedded with a series of hardware algorithms capable of measuring total amount of power energy consumption and estimating the amount of energy consumption of the individual facility equipments, wherein the operating hardware algorithm is an information preprocessing processor of the system which clusters energy information for each individual facility equipments from the raw signal which represents the entire energy information, and the above described processes are summarized as follows.

First, snapshots are extracted from the voltage/current signals, and a reference point is extracted and undergoes noise filtering, and the normal/transition states are classified based on the corresponding results, and through these process the on/off events and the change in the trend of the states are extracted, and then the final clustering data sets are being generated by classifying the loads being matched with the pattern using a voltage/current correlation diagram, a high frequency distortion diagram, a signal change diagram of the current/power snapshot, and an effective/reactive power correlation diagram, and the like that are related to the characteristics of the loads. The generated clustering data sets are transmitted to a specific server or a cloud with unregistered names (for example, load identification such as 1, 2, 3 or A, B, C etc.), which the users may not recognize, through data compression.

Hereinafter it will be described more in detail with reference to FIG. 1. According to FIG. 1, an energy measuring apparatus 100 according to an exemplary embodiment of the present invention includes a power information collecting unit 110, an operating state extracting unit 120, a data set generating unit 130, and a transmitting unit 140.

A power information collecting unit 110 according to an exemplary embodiment of the present invention collects power information containing power signals at least one penetration point of power for the multiple facility equipment.

The facility equipments are electronic equipments including the home appliances using power energy, and penetration point of power is a power input point for the multiple facility equipments according to the exemplary embodiments of the present invention, for example, a house can be a unit. Hereinafter, the operation of the power information collecting unit 110 will be described more in detail with reference to FIG. 2.

In this exemplary embodiment, the power information collecting unit 110 performs a power signal measuring step S112 first. In the power signal measuring step S112 unprocessed power information waveform of the current and the voltage at penetration point of power is being measured as a power signal through the single sensor installed at penetration point of power.

Next, the power information collecting unit 110 performs a snapshot extracting step S114. In the snapshot extracting step S114 collects a voltage or a current snapshot of the periodic alternating current waveform having a period predetermined by said power information. In the present exemplary embodiment, it is advantageous in that a snapshot of one period of waveform for a voltage and a current is being extracted using a high frequency.

Next, the operating state extracting unit 120 according to an exemplary embodiment of the present invention extracts an operating state or the change in the operating state of said facility equipment by classifying normal state or transition state of the power change from the collected said power information. This will be explained more in detail with reference to FIG. 3.

According to FIG. 3, the operating state extracting unit 120 performs a power information and reference point extracting step S116 first. In other words, a real time power usage amount and a power quality information are being extracted, and a reference point is being extracted for classifying the normal or the transition state.

In an exemplary embodiment of the present invention, it is advantageous in that the reference point is a power usage amount, which is consistently used without load variation and always maintaining on-state without on and off in the individual equipment, (obtained) through the extraction of a real time power usage amount and a power quality information

Next, in a transient response separating step S118, a transient response period is extracted wherein the power usage amount is on and off, or the operation state is being changed by the operation of the individual equipments.

Further, in an exemplary embodiment of the present invention, the operation state extracting unit 120 may perform a noise removing step S120. In the noise removing step S120, the meaningless high frequency noise signal generated during the power signal measurement of the total power usage amount is being removed.

In addition, in the operating state extracting unit 120, said snapshots are being classified according to the extracted operating state or the change in the operating state.

Again according to FIG. 3, the snapshots related to the events are being classified in accordance with the individual on/off state prior to clustering for each individual facility equipments through the on/off event detecting step S122.

Next, in a state trend change detecting step S124, besides on/off operating loads, the changing patterns of the operating states for the loads having a multi-step or a continuous changing characteristic are being detected and classified.

After detecting the state trend change, in a total power data processing step S126, a data packet is generated for data calculation, storage, and transmission in relation to the total amount of used energy, the quality information, and the like for a real time power usage service

Next, a data set generating unit 130 according to an exemplary embodiment of the present invention, data sets are being generated for each individual facility equipment which are matched with the said operating states or the changing patterns of the operating states through the signal correlation in accordance with the power consumption characteristic of said individual facility equipments. Hereinafter, it will be described more in detail with reference to FIG. 4.

According to FIG. 4, a data set generating unit performs a load characteristics extracting step S130.

In an exemplary embodiment of the present invention, the signal correlation according to the power consumption characteristics includes a voltage/current correlation diagram, a high frequency distortion diagram, a current/power signal change diagram, and an effective/reactive power correlation diagram, and thus, the load characteristics extracting step S130 extracts signal correlation classification which reflects the power consumption characteristics of the individual facility equipments by utilizing snapshots, transient response, on/off events, and state trend change information extracted from the total power usage data.

Next, the data set generating unit 130 performs on/off event matching and pattern matched load classification for generating the data set.

In other words, in a event matching step S132, on/off events for the individual facility equipments are classified as a pair of identical individual equipments based on the generated signal correlation, and in a pattern matched load classifying step S134, the identical individual equipments having multi-steps and continuous changing characteristics are classified as a on/off event matching related group based on the generated signal correlation.

Next, in a data set generating step S136, grouped data sets are being generated by classifying as the identical equipments in the sub-components inside the individual equipments through on/off event matching and pattern matched load classification.

Once a data set is generated, a transmitting unit 140 transmits the generated data sets to the labeling server 200 which generates labeled power information by recombining the data sets.

Prior to transmission, in an exemplary embodiment of the present invention, data compression may be performed in order to facilitate transmission of a big data packet, which is generated by a series of hardware algorithm embedded in a single sensor single energy measuring apparatus, to a cloud or a specific server for performing software algorithm which is the next process step.

Further, it is also possible to transmit both of the power consumption data and quality information data which are required to perform a realtime power energy information service.

Hereinafter, a labeling server 200, which generates the labeled power information by receiving data sets generated from the energy measuring apparatus 100 according to the above described exemplary embodiments, will be described with reference to FIG. 5.

A labeling server 200 according to an exemplary embodiment of the present invention performs consulting and the like providing energy usage information and saving tips for the power consumers at the final penetration point of power through the processes such as machine learning and automatic labeling and the like based on the received clustering data sets for each individual loads and the realtime power usage and the power quality information data set; it may be a big data processing apparatus embedded with a series of software algorithms which allows various energy saving solutions and consulting by displaying the total energy information measured at penetration point of power and the energy information for each individual facility equipments after receiving data from a single sensor single energy measuring apparatus.

A labeling server 200 according to an exemplary embodiment of the present invention is a post information processing process performing software algorithms, and the process can be summarized as follows. The unregistered load clustering data sets are reclassified into multi-dimensional clustering planes according to the features for each major class facility equipment, and finally classified as on/off, multi-step, continuously changing, and regularly operating loads by defining specific facility equipment classification boundaries through machine learning.

These are mapped to realtime power usage trends in time domain and categorization is completed, and sub-components are grouped (1+2+3 or A+B+C etc.) into the individual facility equipments which are identifiable by the user according to the characteristics of the identical (equivalent) equipments, and then automatic labeling is performed through the naming data sets (refrigerator, washing machine, air conditioner, etc.) collected beforehand and matching algorithms.

At this time, for the loads for which automatic labeling is not performed due to the data sets which are not included in the data sets collected beforehand, the labeling is manually performed through such means wherein the corresponding times are being checked by manually turning on/off the equipment, and the manually generated data sets are again added to the data sets collected beforehand thereby expanding established data sets, and they are used for future automatic labeling.

Displays such as realtime total usage, individual facility equipment usage, energy saving consulting, and the like are provided to users by applying mathematical and psychological analytical algorithms capable of interpreting the collected large capacity big data, analyzing the behavioral patterns, and automatically generating the energy saving tips using (through) the measured total amount of the electric energy, the power information and the power energy usage information for the separated individual facility equipments. Hereinafter, it will be described more in detail with reference to FIG. 5.

According to FIG. 5, the labeling server 200 according to an exemplary embodiment of the present invention includes a receiving unit 201, a recombining unit 220, and a labeling unit 230.

First, the receiving unit 210 receives data sets generated through classification of the power information with reference to the component group constituting the individual facility equipments.

Next, the recombining unit 220 reclassifies the received data sets according to the operating characteristics of said individual facility equipment, and recombines them by mapping according to the time domain.

Prior to this, the recombining unit 220 may perform a data decompressing step S202 first. In other words, when a series of data sets, which are compressed in the energy measuring apparatus 100, are received, the data sets are decompressed in order to apply (perform) software algorithms.

When decompressed, the recombining unit 220 categorizes the reclassified data sets into data sets for each component of said individual facility equipments by mapping the reclassified data sets to the power usage trends in time domain, and recombines said components according to the characteristics of identical facility equipments. This will be described more in detail with reference to FIG. 6.

FIG. 6 is a flow diagram illustrating each step performed in a recombining unit 220 according to an exemplary embodiment of the present invention.

According to FIG. 6, in a major class facility equipment classifying step S204, major class distribution planes are defined according to the load operating characteristics (on/off, multi-step, continuously changing, regularly operating) for the individual facility equipments showing identical load characteristics.

Next, in a characteristics clustering step S206, multi-dimensional planes are reconstructed to facilitate defining of the boundaries within the load distribution plane by combining the load characteristics clustering data sets and the major facility equipment classification.

When a multi-dimensional planes are reconstructed, in a machine learning step S208, the references for load boundary classification are generated by learning through application of machine learning method based on state classification algorithm such as an artificial intelligence network which utilizes the result of the individual load clustering, and data sets are reclassified by performing an individual load extraction for the clustering loads according to boundary setup references where machine learning has been performed based on the continuously updated data and the data collected beforehand through the specific facility equipment boundary setup step S210. In other words, at this time, the detailed load classification of unregistered method is determined up to the sub-components for the individual loads applied within penetration point of power, although the load names are not known in the total amount of power energy.

Next, in a time domain mapping step S212, the data sets for the loads of unregistered name method which are being reclassified as machine learning and specific facility equipment classification boundaries in the clustering multi-dimensional planes, are mapped to realtime data in time domain.

In a categorizing step S214, the sub-components of the individual facility equipments can be finally displayed by classifying the sub-components of the individual facility equipments from the total energy usage at the penetration point of the total power so that users may recognize them, by using a displaying method capable of displaying various colors or data classes for the generated data sets through time domain mapping.

Next, in an identical load recombining step S216, a group, which users may recognize, is generated using the individual facility equipments by combining the sub-components within the individual facility equipments generated in the categorizing step. As an example, the total usage of the individual facility equipments are recombined by combining the characteristics of compressor, motor, lamp, control circuit, and the like which are generated in the categorizing step, and grouping them as a refrigerator (internally, numbers such as 1, 2, 3 and temporary unregistered identifications such as A, B, C are used).

After performing the recombining step, the labeling unit 230 labels the recombined data sets. For example, the name of equipment of the corresponding user is automatically matched for a data set having unregistered temporary identification which is categorized as an individual facility equipment in conjunction with the data sets of the individual facility equipments that has been setup beforehand. For an example, said A, B, C, and the like can be automatically named as refrigerator, TV, washing machine, and the like through a matching algorithm using the data pattern and the stored data.

In addition, in an exemplary embodiment of the present invention, labeling may be manually inputted. In spite of automatic labeling operation, a developer or a user designates names to the equipments for the loads existing with unregistered names due to mismatch with the facility equipment data sets that has been setup beforehand, and manually inputs those names. It is also applicable that a user may record the on/off time of the equipments and perform separately.

In addition, the data sets of the facility equipments that has been setup beforehand may be expanded by separately storing the corresponding data sets with the designated names for the individual facility equipment that had undergone non-categorized load manual labeling.

Further, in the exemplary embodiment of the present invention, the labeling server 200 may provide a data interpretation information on the amount of the energy consumption of the individual facility equipments. In other words, by using behavioral pattern analysis through the data interpretation on the total amount of power energy and the energy usage of the individual facility equipment, and by using the behavioral psychological analytic algorithm based on the power energy change pattern, a behavioral pattern of the user can be generated, thus organizing the data sets for utilizing said pattern becomes possible.

Further, by generating an energy saving tips, and through the big data analysis and the behavioral pattern analysis, automatic generation becomes possible using the expert consulting tip algorithm capable of directing a user for a real energy saving action.

Furthermore, through displaying the total usage in realtime, displaying the estimated usage of the individual facility equipments, and consulting on energy saving, total services for a specific building and a unit house can be provided through the energy IT service providers after installation of the single sensor single energy measuring apparatus.

As an example of various energy consulting where the results obtained through the measuring apparatus and the labeling server may be applied, the ageing state or failure state of the individual facility equipments being determined by detecting the change in the clustering data sets based on the categorization for each sub-components of the individual facility equipments from the total amount of the energy at penetration point of power regarding the states of the individual facility equipments, can be provided to users.

According to the above described exemplary embodiment, although only the total power energy usage information at penetration point of power, from the corresponding information, the energy usage information of the individual facility equipment can be indirectly extracted from the total energy usage information by calculating the power consumption characteristics in accordance with the operation of the sub-components of the various facility equipments and the corresponding load equipments including the individual home appliances being connected to penetration point of power via the hardware and the software algorithms.

Besides, a detailed and accurate high quality energy saving plan can be extracted by extracting the energy usage information of the individual facility equipments when compared with a user feedback that can be provided with the entire total power energy usage information, and the installation space limitation and the burden of facility investment for the expensive solution are reduced since this is a method which is implemented by the various algorithms just by using only a single energy measuring apparatus having a single sensor, not like a method wherein multiple individual energy measuring apparatuses are installed in each individual facility equipments.

Furthermore, not like a method which adopts multiple sensors inside the switchboard, performance enhancement becomes possible together with a reduced facility investment since this is a method acquiring energy usage information for each individual facility equipments above the branch circuit level.

In addition, in extracting energy usage information of the individual facility equipments from the entire electrical energy total usage information measured at penetration point of power, not all the algorithms being used are directly performed in a specific server or a cloud; instead, by separating the measuring equipments (information pre-processing processor, hardware algorithm, clustering data set generating unit which frequently performs complicated computations, and the like) and the clouds (information post-processing processor, software algorithms, labeling and energy saving tip generating units, and the like) into two groups, complicated computations and resource consuming portions are processed in the measuring equipment, thus, only data storage, pattern interpretation, and data utilization, which are the strong features of a cloud or a specific server, are mainly performed, therefore the flexibilities in processing/storing/managing of large capacity big data inside the cloud can be obtained.

Although the foregoing description exemplarily describes the technical spirits of the present invention, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the fundamental characteristics of the present invention.
